Chapter 32: Q. 63 (page 926)

A generator consists of a 12cm by 16cmrectangular loop with 500 turns of wire spinning at 60Hzz in a 25mTuniform magnetic field. The generator output is connected to a series RC circuit consisting of a120ohm resistor and a 35mF capacitor. What is the average power delivered to the circuit?

Short Answer

Expert verified

The average power delivered to the circuit is :-

Pavg=24W

Step by step solution

01

Given information

We have been given that a generator consists of a 12cm by 16cmrectangular loop with 500 turns of wire spinning at 60Hz in a 25mTuniform magnetic field. The generator output is connected to a 120ohmseries RC circuit consisting of a resistor and a 35mFcapacitor. We have to find the average power delivered to the circuit.

02

Simplification

The voltage and current is:

Irms=蔚rmsR2+XC2

蔚o=NBA蝇

=90.48V

To find the expression :

Pavg=Irms2R

=蔚o2R2R2+(1/2蟺fC)2

=(90.48V)2(120惟)2(120惟)2+1/2蟺(60Hz)35脳10-6F2

=24W
